IRIS KashFlow: An Overview

IRIS KashFlow is a UK-focused cloud accounting system designed for small businesses, contractors, and accountants who need straightforward bookkeeping, VAT filing and payroll. The product puts core accounting tasks online so users can create quotes and invoices, reconcile bank transactions, prepare profit and loss reports, and submit VAT returns to HMRC without complex setup.

Compared with rivals like Xero and QuickBooks Online, IRIS KashFlow places stronger emphasis on built-in UK tax compliance and accountant collaboration tools. Xero is often chosen for its broader global banking integrations and app ecosystem, while QuickBooks Online has a larger marketplace of add-ons; IRIS KashFlow narrows focus to core UK requirements, including HMRC Making Tax Digital support, and an accountant-facing portal for white-label client management.

All of this makes IRIS KashFlow a practical choice for UK small businesses and accountants that need a compliance-first, easy-to-use accounting solution, especially where VAT, payroll and direct HMRC submission are priorities.

How IRIS KashFlow Works

IRIS KashFlow runs in the browser and on mobile, storing accounts and transaction data in the cloud so users can work from anywhere. Users create or import customers and suppliers, issue quotes and invoices, record payments, and reconcile bank transactions using connected bank feeds.

VAT returns can be prepared inside the system and submitted directly to HMRC under Making Tax Digital rules, while the built-in payroll module handles employee pay runs and statutory filings. Accountants can access client books via a partner portal that supports branded onboarding and client management.

Practical workflows often start with connecting a business bank account, converting quotes to branded invoices, adding a “pay now” button to speed collections, and using automated reminders to chase overdue amounts, followed by end-of-period reporting and VAT submission.

What does IRIS KashFlow do?

IRIS KashFlow organizes core bookkeeping and compliance tasks into an easy interface, combining invoicing, payments, bank reconciliation, VAT submission, payroll and reporting. Recent product emphasis is on improving payment speed, HMRC MTD compliance, and accountant collaboration through partner tools.

Let’s talk IRIS KashFlow’s Features

Online VAT submissions

Prepare and submit VAT returns directly to HMRC in compliance with Making Tax Digital rules. This simplifies quarterly VAT filing, reduces manual form completion, and maintains a digital VAT record.

Invoicing and quotes

Create branded quotes and convert them into invoices, add a company logo, and include payment buttons on invoices to accelerate collections. Bulk invoice actions and templates reduce repetitive work for recurring billing.

Payments and “Pay Now” buttons

Add multiple payment methods to invoices so customers can pay immediately from the invoice, improving cashflow. The platform integrates with leading payment providers to streamline collections.

Bank feeds and reconciliation

Link bank accounts to automatically import transactions and reconcile them against invoices and expenses, reducing manual data entry and speeding month-end close.

Payroll processing

Run payroll for UK employees, calculate PAYE and National Insurance, and submit required reports to HMRC. The payroll module supports managed payroll options for businesses that prefer outsourcing.

Accountant portal and partner branding

Accountants can manage multiple client accounts, apply white-label branding, and share access for bookkeeping or advisory services, helping firms centralize client workflows.

Reporting and financial insights

Access standard reports such as profit and loss, balance sheet, aged receivables, and stock control to monitor performance and prepare self assessment or company tax figures.

Integrations and partners

Connect to bank feeds, payment gateways and third-party services, and work with IRIS KashFlow Partners for additional services and tooling. Integration options help centralize data and reduce manual reconciliation.

With these features IRIS KashFlow delivers a compact accounting workflow that covers quoting through to tax filing, with the biggest benefit being a UK-centric platform that reduces time spent on bookkeeping and statutory compliance.
